This unique digital plug-on transmitter design will ideally match any microphone or line level source via a standard XLR connector. The DPR-A can tune in coarse or fine steps across the UHF television band from 470.100 to 614.375 MHz for the E01/A1B1 version and from 537.600 to 691.175 for the E01/B1C1 version, with a selectable output power of 25 or 50 mW. The purely digital architecture supports AES 256-CTR encryption for high level security applications.

The transmitter is specially designed with high efficiency digital circuitry for extended operating time on two AA batteries, with status indicated by a multi-color LED. An IR (infrared) port is included to simplify setup with IR enabled receivers. Updates can be made via SD card. The input amplifier uses an ultra low noise op-amp for quiet operation. It is gain controlled with a wide range, dual envelope limiter, providing over 30 dB of headroom above full modulation. A 24-bit A-D converter digitizes the audio, then filters out supersonic noise above 21 kHz.

The DPR-A has an external SMA antenna jack, which accepts Lectrosonics steel flex wire AMM or AMJ series antennas.
